Electric sweeper bag cleaner



April 16, 1935. H. H. EMMONS ELECTRIC SWEEPER BAG CLEANER Patented Apr. 16, 1935 UNITED STATES PATENT OFFlCE 1 Claim.

contents of the bag into an auxiliary inexpensive,

paper or cloth bag, which may be discarded, with its contents, when filled.

A further object of the invention is the provision of a tank equipped with air filtering means, in which the receiving bag is held, eliminating the possibility of the dust escaping to the atmosphere of the room, during the bag cleaning operation.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view illustrating the invention as connected with the dust receiving bag of a vacuum cleaning machine.

Figure 2 is a longitudinal sectional view through the tank, forming a part of the invention.

Figure 3 is a bottom plan view of the cover for the tank.

Referring to the drawing in detail, the reference character 5 designates a vacuum cleaning or sweeping machine, which is supplied with the usual dust receiving bag 6.

The reference character I designates the container or tank, which forms the body portion of the device forming the subject matter of this invention, the tank being provided with an opening in the wall thereof, through which the pipe 8 extends, the pipe 8 having one of its ends secured within the mouth of the bag 9, by means of the elastic band or similar securing means indicated at 0.

It is contemplated to construct the bag 9 of inexpensive paper or cloth material, which may be discarded with its contents, when the bag becomes full.

As clearly shown "by the drawing, the pipe 8 is formed with a bayonet slot ii that accommodates the pin l2 extending from the pipe l3. This pipe I I is formed with an enlarged end portion II that is adapted to be positioned in the clean out opening at one end of the bag, the bag being held on the pipe l3, by the securing band I6.

The container or tank I is provided with a wide ring cover member I! formed with spaced circular flanges l8 that extend over the upper edge of the tank, there being provided a gasket l9 fitted between the flanges insuring an air tight fit between the ring member and tank.

An upwardly and inwardly extended flange I9 is formed on the ring member, and is clamped over the edge of the cover 20, securing the cover to the ring member ll.

Secured to the tank 1 near the upper edge thereof, are spring clips 2| that clamp the edges of the cover 20, removably securing the cover to the tank. v

A bolt 22 is secured to the cover 20 and extends downwardly therefrom, the bolt providing a support for the perforated disc 23, on which the filtering member 24, which is constructed preferably of cloth material, is held.

A nut 25 is secured on the threaded end of the bolt 22, and holds the disc and filtering member in position.

Perforations are also formed in the cover 20 so that the dust ladened air entering the tank may pass'therefrom, after the dust has been filtered, by its contact with the filtering-member.

In the use of the device, when it is desired to remove the material contained in the dust bag of a vacuum cleaner, the enlarged end of the pipe I3 is positioned in the cleanout end of the dust bag, and the dust bag is secured to the pipe. The pipe I3 is now connected with the pipe 8.

It follows that when the motor of the vacuum cleaner is set in operation, the motor will blow the material contained in the bag 6, into the bag 8. t

The air passing through the bag 9 may exhaust to the atmosphere through the filtering member 24 and rings in the cover 20.

When the bag 9 becomes filled, it may be tied and discarded with its contents.

Having thus described the invention, what is claimed is:

In a vacuum cleaning machine, a vacuum cleaner bag, a tank, a cover for the tank, a wide ring member secured to the lower edge of the cover and spaced from the central portion of the cover, said cover having perforations, a perforated disk, a filtering member supported on the perforated disk and held into engagement with the ring member, a bolt extending through the disk and secured to the cover, an air pervious dust bag within the tank, and means for establishing communication between the dust bag and vacuum cleaner bag, whereby the contents of the vacuum cleaner bag may be blown from the vacuum cleaner bag into the dust bag.
